All organisms emit volatile organic compounds (VOCs), which contributes to the volatilome in their environment. Thus, the volatilome is expected to mirror the diversity of the local community. Some of these volatiles are used for chemical communication or chemical recognition processes, other volatiles are repellents and signal danger to the receiver. Although we know about the importance of the VOCs for ecological interactions, only a few studies have been conducted to investigate the significance of entire volatilomes for species composition. Bark and ambrosia beetles are species-rich groups in forests in Germany and known to use chemical cues and signals to find mating partners, associated fungal symbionts and appropriate host trees for oviposition. Thus, these particular group of saproxylic beetle species is a perfect model to investigate the impact of the volatilome on their occurrence in local communities as well as their contribution to the local volatilomes. This will include fungal symbionts as well as natural enemies of the beetles as potential contributors to the complexity of the VOC composition.In our subproject we will investigate whether the volatilome in selected forest patches will represent their local species community. In addition, we will investigate whether the interventions to enhance the structural diversity (ESBC) of the Coordination Project in these forest patches have an impact on the diversity of the VOCs. This will help us to test the hypothesis whether the volatilomes explain the diversity of the saproxylic beetle community. Differences in the specificity of host tree use will help to disentangle the effect of microclimate and the availability of specific tree types on the local community of these beetles. We expect that pest bark and ambrosia beetles will be less abundant in more heterogenous forest patches due to enhanced structural diversity. Finally, we will extend our investigations to the impact of the ESBC on fungal symbionts of selected bark and ambrosia beetles, which we hypothesize to be more diverse in beetle-antagonistic fungi in structurally more diverse forest patches. The latter tests the role of ESBC on the function “insect-microbe symbiosis” and forest protection against bark and ambrosia beetle pests.

所有生物体都会释放挥发性有机化合物（VOC），这有助于其环境中的挥发物。因此，挥发组预计将反映当地社区的多样性。这些挥发物中的一些用于化学通信或化学识别过程，其他挥发物是驱避剂并向接收器发出危险信号。虽然我们知道挥发性有机化合物的生态相互作用的重要性，只有少数研究已经进行了调查的物种组成的整个挥发物组的意义。树皮和豚草甲虫是德国森林中物种丰富的群体，已知它们使用化学线索和信号来寻找交配伙伴、相关的真菌共生体和产卵的适当宿主树木。因此，这些特定的组sagyrylic甲虫物种是一个完美的模型，以调查其发生在当地社区的volatilome的影响，以及他们的贡献，当地volatilome。这将包括真菌共生体以及甲虫的天敌作为潜在的贡献者的VOC composition.In我们的子项目的复杂性，我们将调查是否在选定的森林斑块的挥发组将代表当地的物种群落。此外，我们将调查是否干预，以提高结构多样性（ESBC）的协调项目在这些森林斑块的挥发性有机化合物的多样性产生影响。这将有助于我们检验挥发组是否解释了甲虫群落的多样性。寄主树使用的特异性的差异将有助于解开这些甲虫的当地社区的小气候和特定的树木类型的可用性的影响。我们预计，害虫树皮和豚草甲虫将不那么丰富，由于增强结构多样性的异质性森林补丁。最后，我们将扩大我们的调查，选择树皮和豚草甲虫的真菌共生体的ESBC的影响，我们假设是更多样化的甲虫拮抗真菌在结构上更多样化的森林补丁。后者测试了ESBC在“昆虫-微生物共生”功能和森林保护中对树皮和食心虫害虫的作用。
